  • Patent number: 9321615
    Abstract: A panel hoist and components of various kits including components of a panel hoist are described herein. A panel hoist can be used to hold any of a variety of panels, such as a door attachable to a semi-tractor trailer, and to maneuver the panel for putting into a position for mounting the panel to a panel mounting point or for removing a panel disconnected from a panel mounting point. Various types of suction cups and supplemental panel holders can be used to hold the panel while the panel is moved or prepared for movement. A panel hoist can allow a single person to maneuver panels in various ways instead of having to rely on multiple people to maneuver the panel. Maneuvering the panel can include raising, lowering, or rotating the panel. Various panel hoist components can be configured as a kit.

A ring of metal stock is placed within the jaws of a group of screw-type clamps located on a flat lathe faceplate. The clamps are evenly spaced around the ring of metal stock and each contains one or more pairs of opposing screws. The clamp screws are slowly advanced until the screws gently touch the inner surface and outer surface of the metal stock ring. The opposing screws are then gradually tightened until the ring of metal stock is locked in place. The equal and opposite forces exerted by the opposing screws hold the metal stock rigidly in place without inducing mechanical stresses in the ring that would otherwise warp the ring while it was mounted on the lathe faceplate.

The clamps are particularly useful in clamping the stiles of the face frames of cabinet units which are to be joined together during installation. Each clamp has two jaws, one L-shaped and one I-shaped which, when assembled together, form a U-shape. The jaws are manipulated by a hand operating screw so as to clamp together workpieces such as frame face stiles from opposite sides. A second hand operating screw carries a pressure plate and extends transversely through a threaded opening in the bite portion of the U-shape assembly. The pressure plate acts to clamp workpieces in a front-to-rear direction which are clamped in a side-to-side direction. If desired one of the jaws can be provided with a drill guide so that a hole for a screw can be accurately drilled in stiles or other workpieces that are clamped together and a screw installed while a clamp or clamps remain(s) in place.

A pivotal orienting element is supported by one of the leveling arms and is so manipulatable as to position a universal orientable adjustment element to various selective positions thus allowing adaptability of the mechanism for support and adjustment of different kinds of tubular work pieces such as pipes, tee fittings, 45.

  • Patent number: 4096023
    Abstract: A support assembly including elongated upper and lower parallel plates. A plurality of column supports separate and interconnect the parallel plates. A clamping assembly is supported by the plates, the clamping assembly having vertical and horizontal pressure screw assemblies. A vertical pressure screw assembly is mounted upon the upper plate adjacent each end thereof, and a horizontal pressure screw assembly is mounted upon the lower plate at each end thereof. Both vertical and horizontal pressure screw assemblies project into the space between the upper and lower plates. An annular flexible platform is attached to the lower plate adjacent each end thereof, beneath each vertical pressure screw assembly, and projects into the space between the plates. Lenses, which are to be fixed together by adhesive means to form a combination lens, are received upon a flexible platform, aligned by action of a horizontal pressure screw assembly, and pressed together by action of a vertical pressure screw assembly.

  • Patent number: RE35719
    Abstract: A holding device for vertically positioning a windshield or rear window so that it can be bonded into the frame of a motor vehicle. It has a holding part which can be inserted into a lower transverse part of the frame and a series of support steps transversely spaced from one another in a direction parallel to the transverse part of the frame and pivotally connected to the holding part so that they can individually and elastically pivot out to a holding position or be pressed into an out-of-the way position. The steps each have a support face, the faces being arranged in step wise fashion at an equal vertical distance from each other.
